is set to 1 (TRUE), otherwise in_alarm is set to 0 (FALSE). When

Request.object_request is RQ_REPORT_MASK, then disabled and

in_alarm are set to 1 (TRUE) to indicate that these functions are supported

while all other fields are set to 0 (FALSE).

nviSensorOcc allows an occupancy sensor at another node to be used as

(SNVT_occupancy)

OC_UNOCCUPIED

the occupancy sensor for this node and is typically bound to SensorOcc of

OC_BYPASS

another node. The nviSensorOcc input must show OC_UNOCCUPIED for

OC_STANDBY

3

300 seconds before it is used by the controller for triggering UN_OC

OC_NUL

255

operation. This makes it possible for several occupancy sensors to be

ORed together by binding them all to nviSensorOcc. If any one bound

occupancy sensor shows occupancy, then SensorOcc shows occupancy

for up to 300 seconds after the last sensor shows OC_OCCUPIED. The

valid states have the following meanings: OC_OCCUPIED indicates

occupied. OC_BYPASS, OC_STANDBY, and all unspecified values

indicates the same as OC_OCCUPIED. OC_UNOCCUPIED or OC_NUL

indicates not occupied.

occupancy sensor. The valid states are as follows: OC_OCCUPIED

OC_BYPASS

indicates that the space is occupied. OC_UNOCCUPIED indicates that the

space is not occupied. OC_NUL means no output is available because it is
